i Abpiitantnnied iiafrh afieii': seria'iNa. saazasn To all whom it may concern Zen oic the United btates, residingv at Dayton, Montgomery county, Ohio, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the following is a specification. j y

This invention relates to improvements in hydrocarbon motors and more particularly .to ignition systems for hydrocarbon motors The invention lis adapted for use in various typesl and combinations of ignition systems.

- In the embodiment of the invention here- .in shown, thejignition system includes two separate sources of electric current, alternan ing and direct respectively. A` magneto of the Well known high tension type supplies the alternating' current and a battery sul pliestheg. direct* current, although .a direct y current generator would answer the latter purpose. I f In combining the magneto and 'battery currents as herein shown, a singletrans- -former apparatus and a single interruptor are used forboth circuits; changing device operating in synchronism V with the magnetofsends the battery 'current through the transformer to assist the mag-` neto current. As one 'side of the transformer priniai'ycoil is alwaysgrounded it will be seenthat one side 'or 'thetotherof they battery` will 'always be grounded through said coil so long as the "battery circuit is connected in the system. v

itwill be seen that there may be a greater heating Value to the direct current source, either by reason of its continuing character as distinguished from the momentary char acterfof the magneto current or by reason of rits being of highervoltage for a particular l use, and when the'transformer apparatus of the usual type of magnetois used in this connection, some of its parts may not be made heavyenough to withstand for any ylength of time a current of the heating value or voltageY ofl the',A direct current source. Therefore'such short circuiting ofthe battery as is above pointed out would be liable .sistance and inductance unit is placed in each of the conductors leading from the battery, these, units or coils possessing sufficient resistance and inductance for the purposes required. .Y

The invention is illustrated in the accomypanying drawings,- which form a part of the specification, andin vwhich Figure l is adiagrammatic view of an Vignition systemfinvolving this invention; l .Fig. 2 indicates another form of resistance Wliile'the ignition system herein shown is.k

Referring tothe drawings, l0 indicates l,diagi'ainniatically Va magneto .of `the high tension type having a revolving armature 11 4i'vhicli iiiftliisf instance constitutes a transor secondary coilfl/Q: arid allow' tension or primary coil 13. As shown, the primary and secondary coils il, the transformer aieideiiti'cal with the ia'gneto fari'iiature fcoi-l,`but it will be undertood: that. the severalV functions of separate oil Vand" 'the `"separate'f` coilsare f .within the scopeof thisdescription.rv The coils 12 and 13' 'havejon'e' terminal "connected with a ground '14* and 'their' otherr terminal' of the coil y"'12 connected? `with'a distributer l5, prefoils'are retainedA and both .the combined rerably geared to the armature shaft, and

- successively contacting With brushes 16 devlce.

` which are connected with the respective spark plugs 17 on the motor.y The other terminal of the primary coil 13 is connected by a conductor 18, with one terminal of an interrupter or breaker 19. The conductor 18 is also connected with one side ofa condenser 20, and `withthe brush 21, on the rotating part 21 of a polarity changing de-I vice which may be carried by the armature 11. The other terminal of the interrupter 19 has connected therewith a conductor 22 which is grounded at 23 and connects with the other terminal of the condenser 20. The

other brush 24 onthe revolving part 21 ofy these conductors leading to contacts 29 and Aso 30 of a switclrwhich is also provided with lcontacts 31 and 32.

A suitable source of direct current such as a battery 33 has one terminal connected with the contact 31 through a, conductor 34 in which there is a resistance unit 35, shown in Fig. 1 as a resistance and inductance coil and in Fig. 2 as a simple resistance coil, and

the other terminal connected with the contact 32 through a conductor 36 in Vwhich there is a resistance or resistance and inductance unit 37, which is shownin Fig. 1` `as similar to but need not necessarily be a part of, the unit In Fig. 2 the unit 35 is shown as a simple resistance and the unit 37 as a resistance and inductance unit. If units of the inductance type are used on both sides of the battery andthe coils are woundfon the same magnetic core as shown in Fig. 1, a greater inductive efect is obtained than when separate coils of the same resistance are employed.

When the parts are arranged as shown in Fig. 1, the battery-may be used'as the sources of ignition by connecting the contacts 29 and 32 and the contacts 30and N31, as shown in Fig. 3. When the interrupter 19 is closed, the current will then flow from the battery through the conductor 36 and coil 37, the

segment 25, brush 21,' through the interrupter 19 to the ground 23, returning from ground 22 conductors 28and 34 and coil 35 to the bat'- tery. .When the contacts of the interrupter 19 separate this current rushes via conductor 18 ,through the primary winding 13 where it is transformed and passes from the winding 12 and is delivered to the 'spark plugs as a spark. As the polarity'of the Winding 1 3 reverses with v each half revolution, it is clear ,theme batterathreei'theplerity,change through brush 24, segment 26,

,conductors between Said. seurgg vwill tend to flow from the battery as just described, and if a ground accidentally occurs on either side of the-battery, it will be obvious that the current will be compelled to iow through at least one of these coils35, 37,

and, therefore, a dead ground or short circuit will bel avoided. i

Then it is desired to use magneto ignition only the contacts of the Switch are disconnected, as shown in Fig. l, and when it is desired to interrupt the ignition entirely the contacts 29 and 30 are connected, as shown in Fig. 5.y
